WebMD explains that bacterial infection and gum disease often cause abscesses. Pus collects in the tissues around or beneath the tooth. An abscess often responds to antibiotic treatment, but sometimes it is necessary to drain the infection. If the infection reaches the pulp, or living tissue, of the tooth, a root canal procedure removes the affected area. If this is not successful, the tooth must sometimes be extracted.
